Steven , have you got better now ?   Yeah , the doctor said that I can leave soon . I really miss home .   I guess you miss your wife and children very much .   Yeah , you are right . But I have to stay for another day for observation .   If necessary , I can stay here to accompany you until you are discharged .   No , thanks . I am very grateful that you can come to the hospital to visit me .   You are my best friend . That's what I should do . Please don ’ t be a stranger .
